Perhaps due to cold-war era laws, GSM's security hasn't received the scrutiny it deserves given its popularity. This bothered us enough to take a look; the results were surprising.

The network operators, however, have not woken up to the threat yet. Perhaps the new capabilities to be unleashed this year – like wide-band sniffing and real-time signal processing – will wake them up.
